In a statement from Evick, he explained: "This is a message I never imagined I'd have to post. Tonight in Manchester, NH 3 songs into the set Bret had me sing a song as he rushed off stage.

"In the 9 years I've stood next to him, I've never seen a look like the one on his face as if I was a complete stranger. One of the crew returned instantly to notify me that Bret's blood sugar was extremely low.

"He returned to the stage only to announce that he could not continue."

Sending a shout out 2 all the paramedics both on & off duty who assisted Bret tonight. No words can thank you enough for ur help - Team Bret
